US Patent 11383115 Smart fire extinguisher

Improvements to a portable fire extinguisher where the improvements relate to a system where the owner of the extinguisher can monitor and maintain their fire protection. The improvements also include integration of technology into the fire extinguisher for real-time information of the status around the extinguisher, pre-recorded instructions in one or multiple languages. The technology can also include bi-directional communication whereby a user can communicate to a distant operator. With the inclusion of a speaker the fire extinguisher can provide safety and public service announcements using a wireless WiFi communication network without requiring separate speakers to be wired and connected throughout a building.
